The pair were left bloodied and bruised after their painful encounter with passengers on a coach who turned on them when they realised the gun they were using for their hold-up was fake.

One of the criminals was hit on the head with a rock as an officer arrived to take him away.

And the policeman appeared to show little sympathy for his injuries by grabbing his left wrist - which appeared to have been broken moments earlier when one of the coach passengers kicked him as he sat on the ground - to escort him away.

SHAME: The pair were left bloodied and bruised after their encounter with passengers on a coach

The incident happened around 8am on Saturday morning (September 3) after the two men tried to rob a coach between the cities of Coacalco and Ecatepec in the State of Mexico.

They were held as they tried to flee after one of the passengers discovered the handgun they had threatened a victim with was fake.

The unnamed pair were stripped down to their underwear and assaulted as punishment before police were called.

In June a suspected rapist died after being attacked when locals near the northern Mexican city of Nuevo Laredo, caught him with a young girl he allegedly abused after kidnapping her from a restaurant.
